SABR - shaft design and analysis

SABR allows the user to model transmission shafts, from single section shafts for initial concept sizing to complex multi-node arrangements for full and detailed system analysis, quickly and accurately. 2D CAD can be imported and shaft profiles built up with simple click and drag on the overlaid CAD making complex shaft building trivial.

Stress concentration factors are automatically calculated and can include oil holes, circlip grooves and fillet radii at changes of diameter. Material properties are combined with automatically calculated size and surface finish factors for use in fatigue analysis. The results are plotted on a Haigh diagram using the modified Goodman criteria to give safety factors at every location against infinite life.
